"Polyphasic Systematics of Marine Bacteria" by Rahul Mawlankar is a comprehensive book that delves into the diverse world of marine bacteria, their taxonomy, and their potential applications in various fields. The book highlights the importance of polyphasic systematics, which involves using a combination of phenotypic, genotypic, and chemotaxonomic approaches for bacterial identification and classification. The author emphasizes the significance of 16S rRNA gene sequencing and phylogenetic analysis in determining the evolutionary relationships and taxonomic classification of marine bacteria. The book also provides detailed insights into the microbial diversity of marine environments, bacterial taxonomy, and the various methods used for bacterial identification, including phenotypic and genotypic characterization. Furthermore, the book covers several analytical techniques, including fatty acid profiling, polar lipid profiling, menaquinone profiling, and polyamine profiling, which are used for microbial characterization. It also includes DNA-DNA hybridization and DNA G+C content for assessing the relatedness between different bacterial strains. The author highlights the importance of marine bacteria in bioprospecting, natural products, secondary metabolites, and bioactive compounds, which have potential applications in drug discovery, marine biotechnology, industrial applications, and bioremediation. The book also covers various aspects of marine ecology, biogeography, microbial evolution, adaptation, genetics, and genomics, including culture-dependent and culture-independent methods, molecular techniques, high-throughput sequencing, and bioinformatics. Finally, the book explores the intricate interplay between microbial communities, interactions, symbiosis, quorum sensing, and communication in the marine environment, highlighting the significance of microbial ecology and biogeography. Overall, this book is an invaluable resource for researchers and students interested in marine microbiology and its potential applications in various fields.
